Title: The Innovative Contributions of David A. Gray
Introduction
David A. Gray is a notable inventor based in Santa Clara, California. He has made significant contributions to the field of semiconductor technology, holding three patents to his name. His work focuses on enhancing the efficiency and customization of ASIC (Application-Specific Integrated Circuit) cells.
Latest Patents
One of David A. Gray's latest patents is a method of fabricating an ASIC cell that features multiple contacts. This high-density ASIC cell allows for customization solely at the polysilicon #2 and insulator #3 levels. The design achieves high density by permitting a metal #1 trace to traverse an underlying transistor without requiring space between adjacent transistors. Oversized collector and emitter traces at the polysilicon #1 level make contact with the collector and base regions of the underlying transistor, providing redundant upward contact with collector and emitter polysilicon #2 traces. The design includes a replicated pattern that defines a 3x3 matrix of potential contact points for overlying metal #1 traces to connect with the underlying transistor's emitter, base, and collector. Customization occurs at the metal #1 level and the insulation #3 level by determining which metal #1 traces will contact specific regions of the underlying transistor.
